新的！IEC 60034-14:20 18作为IEC 60034-14:20 18 RLV提供，其中包含国际标准及其红线版本，显示了与上一版本相比技术内容的所有变化。IEC 60034-14:20 18规定了工厂验收振动测试程序和特定条件下某些电机在与任何负载或原动机分离时的振动限值。它适用于DC和三相交流机器，轴高56 mm及以上，额定输出高达50 MW，运行速度为120 min-1至15 000 min-1。与上一版相比，此新版本包括以下重大技术变更:-改进了对“自由悬挂”定义的解释。-增加刚性安装的替代方法-轴键改进选项的定义。

NEW!IEC 60034-14:2018 is available as IEC 60034-14:2018 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC 60034-14:2018 specifies the factory acceptance vibration test procedures and vibration limits for certain electrical machines under specified conditions, when uncoupled from any load or prime mover. It is applicable to DC and three-phase AC machines, with shaft heights 56 mm and higher and a rated output up to 50 MW, at operational speeds from 120 min–1 up to and including 15 000 min–1. This new edition includes the following significant technical changes with respect to the previous edition:
- Improved explanation of the definition “free suspension”.
- Addition of an alternative method of rigid mount
- Definition of an improved option for shaft key.
